The appropriate manuals must be thoroughly studied before

installation, initial start-up and maintenance.

All instructions pertaining to the system and safety must be followed in

full. Non-observance of the instructions may lead to injury to persons

and/or material damage.

HEINZMANN shall not be held liable for any damage caused through

non-observance of instructions.

Independent tests and inspections are of particular importance for all

applications in which a malfunction could result in injury to persons or

material damage.

All examples and data, as well as all other information in this manual

are there solely for the purpose of instruction and they may not be used

for special application without the operator running independent tests

and inspections beforehand.

HEINZMANN does not guarantee, neither expressly nor tacitly, that

the examples, data or other information in this manual is free from

error, complies with industrial standards or fulfils the requirements of

any special application.

To avoid anyinjury to persons and damage to systems, the following

monitoring and protective systems must beprovided:

overspeed protection independent of the rpm controller

HEINZMANN shall not be held liable for any damage caused through

missing or insufficiently rated overspeed protection.

thermal overload protection

The following must also be provided for alternator systems:

Overcurrent protection

Protection against faulty synchronisation for excessively-large

frequency, voltage or phase difference

Directional contactor

The reasons for overspeeding may be:

Failure of positioning device, control unit or its auxiliary devices

Linkage sluggishness and jamming

The following must be observed before an installation:

Always disconnect the electrical mains supply before any interventions

to the system.

Only use cable screening and mains supply connections that

correspond with the European Union EMC Directive

Check the function of all installed protection and monitoring systems

Digital Positioning System 2000

Please observe the following for electronically controlled injection

(MVC):

For common rail systems each injector line must be equipped with a

separate mechanical flow-rate limiter.

For unit pump (PLD) and pump-injector unit (PDE) systems, the

fuel enable is first made possible by the solenoid valve’s control

plunger motion. This means that in the event of the control plunger

sticking, the fuel supply to the injection valve is stopped.

As soon as the positioning device receives power, it can actuate the

controller output shaft automatically at any given time. The range of the

controller shaft or control linkage must therefore be secured against

unauthorised access.

HEINZMANN expressly rejects any implied guarantee pertaining to

any marketability or suitability for a special purpose, including in the

event that HEINZMANN was notified of such a special purpose or the

manual contains a reference to such a special purpose.

HEINZMANN shall not be held liable for any indirect and direct

damage nor for any incidental and consequential damage that results

from application of any of the examples, data or miscellaneous

information as given in this manual.

HEINZMANN shall not provide any guarantee for the design and planning

of the overall technical system. This is a matter of the operator its planners

and its specialist engineers. They are also responsible for checking whether

the performances of our devices match the intended purpose. The operator is

also responsible for a correct initial start-up of the overall system.

1 Safety Instructions and the signal words and symbols used

Digital Positioning System 2000 1

1Safety Instructions and the signal words and symbols used

This publication offers practical safety instructions to indicate the unavoidable residual risks

involved when operating the machine. These residual risks involve hazards to

- Personnel

- Product and machine

- The environment

The primary aim of thesafety instructions is to prevent personal injury!

The signal words used in this publication are specifically designed to direct your attention to possible

damage extent!

DANGER indicates a hazardous situation the consequence of which could

be fatal or severe injuries if it is not prevented.

WARNING indicates a hazardous situation which could lead to fatal

injury or severe injuries if it is not prevented.

CAUTION indicates a hazardous situation which could lead to minor

injuries if it is not prevented.

NOTICE indicates possible material damage.

Safety instructions are not only denoted by a signal word but also by

hazard warning triangles. Red hazard warning triangles indicate

immediate danger to life. Yellow hazard warning triangles indicate a

possible risk to life and limb. Hazard warning triangles can contain

different symbols to illustrate the danger. However, the symbol used is no

substitute for the actual text of the safety instructions. The text must

therefore always be read in full!

1 Safety Instructions and the signal words and symbols used

2 Digital Positioning System 2000

1.1 Safety measures under normal operation

The system may be operated by qualified and authorised personnel only,

who are both familiar with the operating instructions and who can carry

them out!

Before switching on the system, check and ensure that:

only authorised personnel are in the machine’s operating range

no-one can be injured by the machine starting up

Before each start of the motor:

Always check the system for visible damage and ensure it is not put into

operation unless it is in perfect condition! Always notify the responsible

department immediately about any defects

Check and ensure that all safety devices are in proper working condition

Remove all material and objectives surplus to requirements from the operating

range of the system or motor

1.2 Safety measures for maintenance and servicing

Before starting maintenance or repair work:

Block off access to the machine’s working area for unauthorised persons!

Put up an information board that indicates that such work is underway

Switch off main switch for mains supply and secure with a padlock! The key

to the padlock must be held by the person carrying out the maintenance or

repair work

Ensure that all parts that are capable of being touched have cooled down to

ambient temperature and have been isolated from the mains

Re-fasten loose connections

Replace any damaged lines or cables immediately

Keep the switch cabinet closed at all times! Access is solely for authorised

persons with key/tools

Never use a water spray or high-pressure cleaners on switch cabinets and other

electrical equipment enclosures for cleaning purposes! Risk of short circuit

and corrosion to positioning device

2 Application and function

Digital Positioning System 2000 3

2Application and function

2.1 Proper and intended use

The positioning devices StG 2040-PD and StG 2080-PD are to be used solely for control

applications on engines. They are intended for use in an industrial environment. When

operated outdoors, additional protective measures against weather are also required.

Signals are exchanged through electrical signals. Because transmission may be interfered

with by external circumstances or influences, the user must provide additional safety

devices to match the application case.

In individual cases, the following must be coordinated with the manufacturer

HEINZMANN:

Each use which deviates from the above mentioned

Modifications to the device

Use in extreme, ambient conditions that deviate from the specification

(dust, temperature, wetness)

Use under powerful electrical or electromagnetic fields

Use in aggressive atmospheres or vapours

Use in potentially explosive areas

A written opinion from the manufacturer must always be procured in the event of any

obscurities, queries or missing statement.

2.2 Function description

Positioners show a directly proportional correlation between the position of the actuator

output shaft and a command input signal. StG 2040-PD and StG 2080-PD are electrical

positioners with rotating output shaft. They are actuated by an external, electrical position

set point signal, and thereby automatically regulate the mechanical position of their output

shafts. The position set point is transmitted as a current, voltage or PWM signal to each

positioning device. For operation the devices must be connected to an external mains

supply.
